Boyd debuts ROL4000 CDU for Project Deschutes liquid cooling

Boyd showcased the ROL4000 Coolant Distribution Unit (CDU) at the 2025 Open Compute Project Global Summit in San Jose, California.

• Main announcement: Boyd presented the ROL4000 CDU which meets Google’s two-megawatt Project Deschutes CDU requirements, including 2 megawatts cooling capacity, an aggressive 3°C approach temperature difference (ATD), 80 PSI available pressure, 0.2-micron side stream filtration, fully redundant power feeds for each pump circuit, a 230VAC convenience port, and IEEE 519 Ultra Low Harmonic Distortion (ULHD) Variable Frequency Drives for clean facility power.
• Background and details: The ROL4000 is described as a compact, modular retrofit-capable platform intended for enterprise, cloud, and hyperscale data centers, aligned to the Open Compute Project’s interoperable designs; Boyd noted global manufacturing and support across North America, Europe, and Asia Pacific, and promoted modular architecture to simplify integration with existing data center infrastructure.
